INVENTOR IITNESSW ATTORNEY Patented Oct. 7, 1930 SAMUEL STANLEY meson BRONX, new YORK CALENDAR ATTACHMENT FOB WRITING INSTRUMENTALITIES Application filed February 11, 1929. Serial No. 339,112.

This invention relates to improvements in calendars and has particular reference to a calendar for use in connection with writing instrumentalities such as lead pencils and the like.

The primary object of the invention resides in a pencil attachment which fits over the end of a lead pencil to protect the pointed end of the same when the pencil is not in use, and

10 which may be transferred to the opposite end when the pencil is in use, the said attachment containing a calendar strip by which the current month of a yearmay be displayed for instant reference. As the months pass,

the past month may be torn from the strip and the same reset to expose the next succeeding month, and when the entire calendar strip has been used, a new one may be substituted therefor for the next succeeding year without dispensing with any of the other parts.

Another object of the invention is to provide a pencil attachment in which a calendar strip is housed within a cylinder provided with a slot by which the outer end of the same may be wound about the exterior of the cylinder to expose a calendar month, the exposed portion being protected by a trans parent window which fully encloses the same.

A further object is the provision of a pencil calendar attachment which is simple in construction, inexpensive of manufacture, and attractive in appearance.

With these and other objects in view, the invention resides in certain novel construction and combination and arrangement of parts, the essential features of which are here inafter fully described, are particularly pointed out in the appended claims, and are illustrated in the accompanying drawing, in which Figure 1 is a perspective View of my calendar attachment in applied position upon a pencil.

Figure 2 is an enlarged vertical sectional Figure 4 is a perspective view of the calendar attachment with parts in separated position.

Referring to the drawing by reference characters, the numeral 10 designates my calendar attachment in its entirety which includes a tubular sleeve 11, split inwardly from its outer free edge as at 12 to provide resilient walls by which the same may be inserted upon either end of a lead pencil 13. Secured to the sleeve 11 is a transparent cylinder 1 1,

preferably constructed of isinglass or other non-breakable glass, and which in turn is secured to a threaded collar 15.

A removable cylinder 16 is insertible through the collar 15 and is of a diameter less than the inner. diameter of the collar to cylinder is retained in operative position.

The side wall of the cylinder is provided with a longitudinal slot 19, through which one end of a spirally wound paper calendar strip" :20

extends; The strip contains spaced monthly calendars for the successive months of a calendar year and each calendar month is of a width to wrap around the exterior of the cylinder 16 to only expose that particular month and which registers with the trans parent cylinder 14 when the cylinder is screwed homein the collar 15. The transparent cylinder protects the exposed portion of the calendar strip and permits a clear view of the same for reference purposes.

To change the calendar month, it is only necessary to unscrew the cylinder 16 from the collar 15, tear off the past calendar month, and pull out upon the strip until the next succeeding month is exposed by winding it once around the cylinder, and replacing the same in the manner already explained. It will be appreciated that when the calendar attachment is in an applied position upon a pencil as shown in Figure 1 of the drawing, the same will prove useful when reference is required of the days of a current month at times when other calendars are not accessible.

WVhile I have described what I deem to be the most desirable embodiment of my invention, it is obvious that many ofthe details may be varied without in any way departing from the spirit of my invention, and I therefore do not limit myself to the exact details of construction herein set forth nor to anything less than the whole of my invent-ion limited only by the appended claims.

What is claimed as new is 1. A calendar attachment for writing instrumentalities comprising a sleeve member having a transparent tubular wall, a cylinder supported within said sleeve, and a calendar strip wound within said cylinder and having a portion thereof passing through a slot therein and wound about the exterior of said cylinder to expose the calendar indicia thereon through said transparent wall.

2. A calendar attachment for writing instrumentalities including a tubular structure having a transparent circumferential window, a cylinder housable in said tubular structure and provided with a longitudinal slot in register with said window, and a calendar strip wound within said cylinder with one end passing through saidslot and wound about the exterior of said cylinder to expose the calendar indicia thereon through said transparent window.

3. A calendar attachment for writing instrumentalities comprising a tubular sleeve, a transparent cylinder secured to one end of said sleeve, a threaded collar secured to said transparent cylinder, a cylinder threaded to said collar and having a slot therein in register with said transparent cylinder, and a calendar strip spirally wound within said cylinder having its free end passingthrough said slot and wound about the exterior of said cylinder for visibly displaying calenda r indicia through said transparent cylinder.

In testimony whereof I have afiixed my signature.
